One question that trumped me was: if you were a prime minister for a day, what one law would you change and why?

The Constitution. Whatever you write in there, all other laws and regulations will have to be adjusted and you do not have to worry about it. It is hard for the Prime Minister to change it, but if you can - it is the best choice.

A law that forbid hiring employee in related bonds. Reasons^ 1. More healthy competetion 2. More chances to get a nice job by people who haven't nice relations

For election day - only tax payers could vote. As citizens who pay taxes generally responsible for their decisions.

Cancel the deduction of Income tax on earnings. Increase the retail tax for businesses. The more money people have the more they will spend and this in turn will increase the economy, create more jobs

I would reinstate the death penalty for traitors (repelled, in Canada, very discreetly by traitorous politicians. Less than 25 years ago...) and then start cleaning up the place (again, Canada.)
